Abstract

A sheet processing apparatus includes, a punch unit configured to perform punching processing on a sheet conveyed from one of a plurality of sheet storing units capable of storing a sheet or a pre-punched sheet, an input unit configured to input a number of holes punched in the pre-punched sheet stored in one of the sheet storing units, an acquisition unit configured to acquire a number of holes that can be punched by the punch unit, a determination unit configured to determine whether the input number of holes coincides with the acquired number of holes that can be punched, and a control unit configured to display a predetermined warning in a case where the determination unit determines that the input number of holes does not coincide with the acquired number of holes that can be punched.

What is claimed is: 
     
       1. A sheet processing apparatus comprising:
 a puncher configured to punch holes in a first sheet conveyed from one of a plurality of sheet storing units; 
 a discharge roller configured to discharge the first sheet having the holes punched by the puncher and a second sheet conveyed from other of the plurality of sheet storing unit, the second sheet being a pre-punched sheet; 
 a processor; and 
 a memory storing instructions which, when executed by the processor, cause the sheet processing apparatus to:
 acquire a number of holes of the second sheet; 
 acquire a number of holes of the first sheet to be punched by the puncher; 
 determine whether the acquired number of holes of the second sheet coincides with the acquired number of holes of the first sheet to be punched; and 
 display a predetermined warning in a case where it is determined that the acquired number of holes of the second sheet does not coincide with the acquired number of holes of the first sheet to be punched. 
 
 
     
     
       2. The sheet processing apparatus according to  claim 1 , wherein the predetermined warning is a message indicating that a position of a hole of the second sheet does not coincide with a position of a hole to be punched in the first sheet. 
     
     
       3. The sheet processing apparatus according to  claim 1 , wherein the warning is a graphic indicating that a position of a hole of the second sheet does not coincide with a position of a hole to be punched in the first sheet. 
     
     
       4. The sheet processing apparatus according to  claim 1 , wherein the pre-punched sheet is a tab sheet. 
     
     
       5. The sheet processing apparatus according to  claim 1 , wherein the processor does not cause the puncher to punch the holes in the first sheet in a case where it is determined that the acquired number of holes of the second sheet does not coincide with the acquired number of holes of the first sheet to be punched. 
     
     
       6. The sheet processing apparatus according to  claim 1 ,
 wherein the processor selects one of the sheet storing units as a conveyance source of the first sheet based on the acquired number of holes of the second sheet and the acquired number of holes of the first sheet in a case where sheet processing using the second sheet is performed. 
 
     
     
       7. A method for controlling a sheet processing apparatus including a plurality of sheet storing units and a puncher configured to punch holes in a first sheet conveyed from one of the sheet storing units, the method comprising:
 discharging the first sheet having the holes punched by the puncher and a second sheet conveyed from other of the plurality of sheet storing unit, the second sheet being a pre-punched sheet; 
 acquiring a number of holes of the second sheet; 
 acquiring a number of holes of the first sheet to be punched by the puncher; 
 determining whether the acquired number of holes of the second sheet coincides with the acquired number of holes of the first sheet to be punched; and 
 displaying a predetermined warning in a case where it is determined that the acquired number of holes of the second sheet does not coincide with the acquired number of holes of the first sheet to be punched. 
 
     
     
       8. The sheet processing apparatus according to  claim 1 ,
 wherein the processor deactivates the second sheet insertion setting in a case where it is determined that the acquired number of holes of the second sheet does not coincide with the acquired number of holes of the first sheet to be punched. 
 
     
     
       9. The sheet processing apparatus according to  claim 1 , wherein, in a case where the acquired number of holes of the second sheet does not coincide with the acquired number of holes of the first sheet, the first sheet is not conveyed from the one of the plurality of sheet storing units. 
     
     
       10. The sheet processing apparatus according to  claim 1 , wherein the processor selects a sheet storing unit from the sheet storing units as a conveyance source of the first sheet or the second sheet. 
     
     
       11. The sheet processing apparatus according to  claim 1 , wherein the processor sets a punch attribute of the second sheet. 
     
     
       12. The sheet processing apparatus according to  claim 11 , wherein the punch attribute includes the number, size, and position of the holes of the second sheet. 
     
     
       13. The sheet processing apparatus according to  claim 1 , wherein, in a case where a job to discharge the first sheet and the second sheet is specified, the processor determines whether the acquired number of holes of the second sheet coincides with the acquired number of holes of the first sheet to be punched. 
     
     
       14. An image forming apparatus comprising:
 a first feeder configured to feed a first sheet; 
 a second feeder configured to feed a second sheet, the second sheet being a pre-punched sheet; 
 a printer configured to print an image on the first sheet fed by the first feeder; 
 a puncher configured to punch holes in the first sheet on which the image is printed by the printer; 
 a discharge roller configured to discharge the first sheet having the holes punched by the puncher and the second sheet fed by the second feeder; 
 a processor; and 
 a memory storing instructions which, when executed by the processor, cause the sheet processing apparatus to:
 acquire a number of holes of the second sheet to be fed by the second feeder; 
 acquire a number of holes of the first sheet to be punched by the puncher; 
 determine whether the acquired number of holes of the second sheet coincides with the acquired number of holes of the first sheet to be punched; and 
 display a warning in a case where the acquired number of holes of the second sheet does not coincide with the acquired number of holes of the first sheet to be punched, 
 
 wherein, in a case where the acquired number of holes of the second sheet coincides with the acquired number of holes of the first sheet to be punched, the first sheet and the second sheet are discharged by the discharged roller.
